* filter testing available on the ProOne website is for the G2.0 although the G3.0 is most updated product available

** includes Lead, Arsenic, Mercury, Copper, Chromium, Selenium

*** Berkey requires additional filter for fluoride and arsenic filtration; may leach aluminum oxide back into water, though under ... limits.

**** water quality and hardness may affect filter life & replacement frequency, as well as filter frequency per day

Be sure to review the manufacturer performance data sheets and third-party testing of each water filtration system for all the details on safety, performance, and filtration efficacy.
